IMPRQVEMENT IN MACHINERY FOR PLOWlNG AND TILLING LAND BY STEAM.

Specification forming part of Letters Patent No. 32,026, dated April 9,1861.

To all whom it may concern:

Be it known that I, JOHN FOWLER, Havering, in the county of Essex,England, have invented a new and useful Improvement in Machinery forPlowing and Tillin g Land by Steam and I do hereby declare that thefollowing is a full, clear, and exact description thereof, referencebeing bad to the accompanying drawings, making part of thisspecification, in which-5 Figure 1 is a plan, and Fig. 2 a longitudinalvertical section.

The same letters indicate like parts inboth the figures.

My said invention relates to that class of machinery for. plowing andtilling land by steam in which a locomotive steam-engine moves at givenintervals along one edge of the field, and ropes pass from the engine toand around a pulley in a carriage termed an an chor, which is moved atintervals along the opposite edge of the field, the said ropes from theengine being attached to plows or other tilling instruments to draw themacross the field alternately in opposite direction.

Prior to my said invention the anchor-carriage was moved at intervals bymanual power; and the object of my said invention is to impart thismotion by the power of the engine at the opposite side of the field bycombining with the pulley on the anchor-carriage around which the ropepasses to operate the plows or other instruments, and with the drum orcapstan of a rope or chain connected wit-h an anchor secured in ahead ofthe anchor-carriage, mechanism to operate the said drum or capstem atthe required intervals to advance the anchor-carriage by the motion ofthepulley derived from the engine.

In theaccompanying drawings, A represents whatis termed theanchor-carriage, mounted on four wheels, B, made sufficiently thin atthe periphery to cut into the land to present the an interposed requiredresistance to thelateral pull in drawing the plows or other implementsacross the field. In thiscarriage there is a grooved pulley, to, aroundwhich the rope from the engine is to pass. The shaft of the pulley 00carries a bevel-pinion, b, which engages a corresponding bevel-pinion,c,on a horizontal shaft, 01, which carries a worm, d,.the threads of whichen gage the cogs of a horizontal worm-wheel, 0;

Jr., of

the ground some distance and this worm-wheel is provided with bevelcogsc to impart motion by another bevelwheel, f, to a horizontal shaft,which carries a spur-wheel, g, that engages a spur-pinion, h, on theshaft of which there is mounted a drum, 2', that is to receive and windup a rope attached to an anchor or other fastening some distance aheadofthe carriage. This drum turns freely on the shaft and carries aratchet-hand or pawl, which takes into the teeth ofa ratchetwheel faston the shaft of the drum, so that motion is imparted to the drum in thedirection of the arrow by the ratchet-wheel acting on the ratchet-handor pawl. In this way it will be seen that motion is communicated fromthe pulley a (impelled by the rope from the engine) to the drumi to windup the anchor-rope on the drum, and thereby draw the anchorcarriageforward. It is proper that this movementshouldtake place while the plowsorother implements are traveling toward the engine, and that the anchoror carriage should be advanced during the return toward the engine. Forthis purpose there is only a segment of the worm-wheel e cogged, asrepresented, so that when the uncogged segment reaches the worm themovement ofthe carriage shall stop. By simply lifting the pawl t by handthe train of wheels are liberated so that they can be turned by handwhen required to re-engage the wheel 6 with the worm.

And, although I have above described the modeof application which I havereduced to successful practice, I do not wish to be under stood aslimiting my claim of invention to such mode of application, as therequired connec tion between the pulley impelled by the rope from theengine and the drum which winds up the anchor-rope can be effected byother and equivalent mechanical means.

What I claim as my invention, and desire to secure by Letters Patent,is-- Oombinin g the pulley on the anchorearriage, which receives motionfrom the engine by the pulling of the plows or other implements, withthe drum that operates the anchor-rope by means of the intermediatemechanism herein described, or any equivalent therefor, as described,and for the purpose set forth.
